SAND in Action: Subsequence Anomaly Detection for Streams

Summary: Online, domain-agnostic subsequence anomaly detection for streams. SAND incrementally updates a drift-adaptive model, discards obsolete data, and avoids full-data access, enabling real-time subsequence anomaly detection and robust performance against competing streaming methods.
